FI and his ex have an adorable dtr, who will be a flower girl in our wedding in early May. His ex is getting married at the end of May. They've started the preliminary talks about how to arrange drop off/pick up for the weddings. We usually meet his ex Sunday evenings, which would be right after our wedding. Silly me, I just assumed his parents would meet his ex on June 3rd.....but she's wanting to attend OUR wedding! AND naturally assumes, that we will attend hers. Just a little background - she's a *VERY* emotional woman, who loves to be in the spotlight....she talks loud, she laughs loud, she cries loud (she cries A LOT), she gets "sick" often..... *sigh* It's exhausting watching her! (FI, his ex, and I worked together 10+ years ago, and she hasn't changed a bit from being a teenager!)So....what do I do? I've never liked this woman, and were she not future step-dtr's mom would never in a million years want her anywhere near my wedding....but she is future step-dtr's mom and I want to maintain a friendly-in-front-of-the-kid-only relationship. FI is not very helpful. He would prefer her not be there, but wants to avoid any drama. My family and friends are split....
